Abstract: A switching device for a temperature switch or pressure switch has, in a housing (1), a snap-action switch (6) which has a contact rivet (14) which is always held against one of two fixed contacts (11, 12) by means of a contact spring (15). The snap-action switch (6) is operated by means of an operating lever (21) which is displaced by a plunger (5). A compression spring (29) is used to reset the plunger (5). This compression spring (29) is supported on the operating lever (21), above the plunger (5), and on an end insulating material panel (7) of the housing (1) of the switching device. In order to make possible this arrangement of the compression spring, a slot-shaped passage (28) is provided in a tongue (16) of the contact spring (15), and the compression spring (29) is guided through said passage (28). <IMAGE>

Title: Radio-frequency surgical instrument
Inventor: MEIER REIMUND DIPL ING
IPC: A61B18/12
Filed: 1983-10-22
Abstract: The invention relates to a radio-frequency surgical instrument having a radio-frequency generator as well as at least in each case one electrode terminal for monopolar active electrodes, bipolar electrodes and a neutral electrode and a control device for switching over between bipolar and monopolar operating modes. The aim of the radio frequency surgical instrument is to enable both monopolar coagulation and monopolar cutting in the range of relatively high outputs, as well as to enable bipolar coagulation by means of relatively low output. In this case, the operational outlay is to be low, but on the other hand the electric safety for the patient and the operator is to be high, in like fashion. This is achieved according to the invention when the signals produced by the radio frequency generator are fed to a first amplifier stage to the output of which the primary winding of a first transformer, whose secondary winding is directly connected to the bipolar electrode terminal, is connected with the interposition of contacts, on the one hand, and on the other hand the primary winding of a second transformer is connected with the interposition of contacts, the secondary winding of the second transformer acting on the input of a second amplifier stage whose output is connected to the electrode terminals for the monopolar active electrode and the neutral electrode. <IMAGE>

Title: Method and arrangement for the monitoring of positioning sensors
Inventor: FABER WILFRIED
IPC: B23K9/127
Filed: 1984-01-30
Abstract: The invention relates to a method for the monitoring of positioning sensors during welding, which allows a check of their functioning and operational reliability, and to an arrangement for carrying out the method. The object is to detect defects or inadmissible operating states on the sensor head or on the transmission part, in order to prevent faults in the apparatus technology used. A method and an arrangement are therefore to be developed which check the functioning of the positioning sensors used during the welding, prevent incorrrect information and signal faults. According to the invention, the current consumption necessary for this takes place via three suitable threshold switches and the logical evaluation of the binary signals by serial linkage, in such a way that the mode of operation of the positioning sensor is checked via the size of the signal obtained, the entire range being subdivided into four sub-ranges in order to detect different operating states. The method is carried out by means of an arrangement of suitable technical means.

Title: Thermal print head
Inventor: REIN WOLF-HEIDER DR ING
IPC: B41J2/335
Filed: 1984-06-16
Abstract: In thermal print heads for high printing capacity, the residual heat which is not transmitted to the recording medium must be conducted away by the time the heating element is energised again.

Hydraulically operated clamping devices on the movable body parts releasably hold the extrusion die in position.
Patent DE-3427088-A1 (DE)
Inventor: PAPST GERO
IPC: C10J3/84
Filed: 1984-07-18
Abstract: An apparatus for cooling a hot product gas, the latter is passed through a tubular zone. The product gas contains particles which, on entering the tubular zone, are tacky, but lose their tackiness through cooling in said zone. Within said zone a cooling gas flow forms a gas wall, which prevents contact between the product gas or the tacky particles contained therein, and one of the fixed walls in the tubular zone. Thus within an outlet connection (2) forming the tubular zone is provided an anular insert (3), which forms a gap (4) with the outlet connection. A cooling gas is blown into this gap counter to the flow direction of the product gas. At the end of the insert, this cooling gas is deflected by the product gas and flows within the insert in the same direction as the product gas and protects the inner wall of the insert from the latter. This product gas is cooled to such an extent by the action of the cooling gas that the particles in the product gas have lost their tackiness at the outlet-side end of the insert.

Abstract: A device for automatically filling in a gambling ticket by means of card issued for an owner comprises a scanning device for detecting the position and type of the gambling ticket introduced into the device and a processor which emits actuating signals to positioning devices for positioning the gambling ticket in dependence on position-control signals emitted by the scanning device. In addition, the processor drives a printing unit which prints on the gambling ticket in dependence on the information recorded on the card. The detection of a wide variety of types of gambling ticket and a correspondingly exact filling-in of the gambling ticket are possible by virtue of sensors fitted on the print head of the printing unit. Additional on-line connections to a central lottery or pools company permits direct data traffic with the peripheral printing units.
